Saturday's much-anticipated return of the Sheffield Shield will see some big-name inclusions across the country.
New South Wales welcome back Nathan Lyon and Nic Maddinson after sat out the match against Queensland prior to Christmas.
Chris Lynn will make his return for the Bulls after shoulder surgery forced him out of the first half of the season, while Michael Philipson and Charlie Hemphrey are likely to make their debuts for Queensland in the place of the injured Usman Khawaja and opening batsman Marnus Labuschagne.
Kane Richardson, Adam Zampa and Rookie Alex Ross, who will debut if named in the XI, come into the Redbacks squad for the injured Chadd Sayers and omitted Johan Botha and Sam Raphael.
Alex Doolan will lead the Tigers in the absence of regular leadership duo George Bailey and Xavier Doherty who, alongside James Faulkner, are with the Australian team preparing for the 2015 ICC Cricket World Cup.
Australian fast bowling pair Peter Siddle and James Pattinson have been named alongside one-another in Victoria's squad for the first time in 27 months, as the latter prepares for his first Shield appearance since January 2013.
Marcus Stoinis and Chris Rogers also come into the squad for Glenn Maxwell and Aaron Finch, who are unavailable with international duties.
Ryan Duffield comes into the WA squad for the first time since the 2013-14 Shield final, after picking up a hamstring injury in August.
The left-arm quick replaces Jason Behrendorff, who just received the news that a stress fracture in his lower back is season ending.
Victoria head into the sixth round of Shield matches 6.2 points clear of Western Australia at the top of the table.
